--- # NOTE(mgoddard): Currently (just prior to Stein release), sending SIGHUP to # nova compute services leaves them in a broken state in which they cannot # start new instances. The following error is seen in the logs: # "In shutdown, no new events can be scheduled" # To work around this we restart the nova-compute services. # Speaking to the nova team, this seems to be an issue in oslo.service, # with a fix proposed here: https://review.openstack.org/#/c/641907. # This issue also seems to affect the proxy services, which exit non-zero in # reponse to a SIGHUP, so restart those too. # The issue actually affects all nova services, since they remain with RPC # version pinned to the previous release: # https://bugs.launchpad.net/kolla-ansible/+bug/1833069. # TODO(mgoddard): Use SIGHUP when this bug has been fixed. # NOTE(mgoddard): We use recreate_or_restart_container to cover the case where # nova_safety_upgrade is "yes", and we need to recreate all containers. # FIXME(mgoddard): Need to always do this since nova-compute handlers will not # generally fire on controllers. - name: Reload nova cell services to remove RPC version cap vars: service: "{{ nova_cell_services[item] }}" become: true kolla_docker: action: "recreate_or_restart_container" common_options: "{{ docker_common_options }}" name: "{{ service.container_name }}" image: "{{ service.image }}" environment: "{{ service.environment|default(omit) }}" pid_mode: "{{ service.pid_mode|default('') }}" ipc_mode: "{{ service.ipc_mode|default(omit) }}" privileged: "{{ service.privileged | default(False) }}" volumes: "{{ service.volumes|reject('equalto', '')|list }}" dimensions: "{{ service.dimensions }}" healthcheck: "{{ service.healthcheck | default(omit) }}" when: - kolla_action == 'upgrade' - inventory_hostname in groups[service.group] - service.enabled | bool with_items: "{{ nova_cell_services_require_nova_conf }}"
